<a href="%pathto:sift.vl_plotsiftdescriptor;">VL_PLOTSIFTDESCRIPTOR</a>(D) plots the SIFT descriptors D, stored as
columns of the matrix D. D has the same format used by <a href="%pathto:sift.vl_sift;">VL_SIFT</a>().
</p><p>
<a href="%pathto:sift.vl_plotsiftdescriptor;">VL_PLOTSIFTDESCRIPTOR</a>(D,F) plots the SIFT descriptors warped to
the SIFT frames F, specified as columns of the matrix F. F has the
same format used by <a href="%pathto:sift.vl_sift;">VL_SIFT</a>().
</p><p>
H=<a href="%pathto:sift.vl_plotsiftdescriptor;">VL_PLOTSIFTDESCRIPTOR</a>(...) returns the handle H to the line drawing
representing the descriptors.
</p><p>
REMARK. By default, the function assumes descriptors with 4x4
spatial bins and 8 orientation bins (Lowe's default.)
</p><p>
The function supports the following options
</p><dl><dt>
NumSpatialBins
<span class="defaults">[4]</span></dt><dd><p>
Number of spatial bins in each spatial direction.
</p></dd><dt>
NumOrientBins
<span class="defaults">[8]</span></dt><dd><p>
Number of orientation bis.
</p></dd><dt>
Magnif
<span class="defaults">[3]</span></dt><dd><p>
Magnification factor.
